To remediate the misconfiguration “Ensure API Keys Are Rotated Periodically” for GCP using GCP CLI, follow the below steps:

1. Open the Cloud Shell in the GCP console.

2. Run the following command to list all the service accounts in the project:

   gcloud iam service-accounts list
   

3. Select the service account for which you want to rotate the API keys.

4. Run the following command to list all the keys for the selected service account:

   gcloud iam service-accounts keys list --iam-account [SERVICE_ACCOUNT_EMAIL]
   

   Replace [SERVICE_ACCOUNT_EMAIL] with the email address of the service account.

5. Identify the key that needs to be rotated and note down its ID.

6. Run the following command to delete the key:

   gcloud iam service-accounts keys delete [KEY_ID] --iam-account [SERVICE_ACCOUNT_EMAIL]
   

   Replace [KEY_ID] with the ID of the key to be deleted and [SERVICE_ACCOUNT_EMAIL] with the email address of the service account.

7. Run the following command to create a new key:

   gcloud iam service-accounts keys create [OUTPUT_FILE] --iam-account [SERVICE_ACCOUNT_EMAIL]
   

   Replace [OUTPUT_FILE] with the name of the file to which the new key will be written and [SERVICE_ACCOUNT_EMAIL] with the email address of the service account.

8. Set a reminder to periodically rotate the API keys for all the service accounts in the project.

By following these steps, you can remediate the misconfiguration “Ensure API Keys Are Rotated Periodically” for GCP using GCP CLI.

To remediate the misconfiguration “Ensure API Keys Are Rotated Periodically” for GCP using Python, you can follow the below steps:

1. First, we need to list all the API keys that are present in the GCP project. This can be done using the google-auth and google-api-python-client Python libraries.

from google.oauth2 import service_account
from googleapiclient.discovery import build

# Set the credentials
creds = service_account.Credentials.from_service_account_file('<path_to_service_account_key_file>')

# Build the GCP service object
service = build('cloudkms', 'v1', credentials=creds)

# List all the API keys in the project
keys = service.projects().locations().keyRings().cryptoKeys().list(parent='projects/<project_id>/locations/global/keyRings/<key_ring_name>').execute()

2. Once we have the list of API keys, we can check the creation time of each key using the keyVersion API.

# Loop through each key and check its creation time
for key in keys['cryptoKeys']:
    key_versions = service.projects().locations().keyRings().cryptoKeys().cryptoKeyVersions().list(parent=key['name']).execute()
    for key_version in key_versions['cryptoKeyVersions']:
        create_time = key_version['createTime']
        # Check if the key is older than the rotation period (e.g. 90 days)
        # If it is, then rotate the key

3. If the key is older than the rotation period (e.g. 90 days), we can rotate the key by creating a new key version and setting it as the primary version.

# Create a new key version
new_version = service.projects().locations().keyRings().cryptoKeys().cryptoKeyVersions().create(parent=key['name'], body={}).execute()

# Set the new version as the primary version
service.projects().locations().keyRings().cryptoKeys().updatePrimaryVersion(name=key['name'], body={'cryptoKeyVersionId': new_version['name'].split('/')[-1]}).execute()

4. Finally, we can log the details of the key rotation for auditing purposes.

# Log the key rotation details
logging.info(f"Rotated API key {key['name']} with new version {new_version['name']} created at {new_version['createTime']}")

Note: You will need to replace <path_to_service_account_key_file> with the path to your GCP service account key file, <project_id> with your GCP project ID, and <key_ring_name> with the name of the key ring that contains the API keys. You will also need to adjust the rotation period as per your organization’s policies.
